Device for winding and unwinding the lower part of fishing line

ABSTRACT

Device for winding and unwinding the lower part of fishing line (cast) is a part of equipment for fishing with hook, by which it is solved the problem of visibility in water of lower reinforced parts of lines made of materials visible in water. These parts represent one of the most loaded parts of fishing equipment, because they are subjected to big tensile and gliding stresses. FIG.  3.  shows the device ( 1 ) consisting of a two-part housing in which there is the hollow cylinder ( 14 ) on which the reinforced lower part of the line ( 21 ) is wound by means of a blade coil spring ( 15 ). In the stage of attracting the fish, the reinforced lower part of the line ( 21 ) remains invisible and in the stage of swallowing, tearing and pulling the bait with the device ( 1 ), reinforced lower part of the line ( 21 ) is pulled out of the device ( 1 ). The pulled out, reinforced lower part of the line ( 21 ) can not be bitten through or torn off by the fish, that enables the reliable catch. The device is used as the bait and model or insert for natural and artificial fishing baits for fishing predatory freshwater and sea fish.

TECHNICAL FIELDS

The subject of inventionis the device for winding and unwinding thelower part of fishing line, used as a bait or insert for natural andartificial fishing baits for fishing predatory freshwater and sea fish.

According to the seventh edition of the International Classification ofPatents, the invention belongs to the fields of technique, marked asfollows:

-   A01K-91/14—casts,-   A01K-91/16—casts for fishing bait throwing,-   A01K-91/06—devices on lines that are not foreseen on another place,    e.g. for automatic hook piercing,-   A01K-91/08—devices on lines for angling by dragging,-   A01K-91/10—devices on lines for automatic hook's piercing,-   A01K-83/06—devices for holding baits on the hook.

TECHNICAL PROBLEM

Fishing by hook of predatory frishwater and sea fish is from theeconomic standpoint the most profitable and from the sports standpointthe most attractive. Predatory fishes belong to the range of largest andstrongest fishes for which there is necessary the equipment of specialmake, in order to attract fish of prey and to hold them on a hook tilldrawing them out of water. Predatory fish have in their jaws bonegrowths in form of teeth for cutting and tearing the catches. Thereforethese lower parts of line resp. casts., represent one of most loadedpart of fishing equipment for fishing predatory fish, because they aresubjected to large tensile and gliding strains. Lines in general shouldbe made of transparent materials, invisible in water, so that baits onlines would leave as natural as possible impression. As there are notavailable materials for line with high tensile and gliding strengthinvisible in water, the lower, the most strained parts of line are madeof metal, nontransparent materials. Visible casts made of metalprotruding from artificial or natural bait, decrease the attractivenessof the bait and thus the entire fishing as economic or sport activity.Therefore it is put the technical problem of device manufacture thatwould the lower reinforced nontransparent metal part of the line, makeinvisiblein the stage of attracting fish and effective and resistant tobig tensile and gliding strains in stages of swallowing, pulling off anddragging the bait.

BACKGROUND ART

On the modern market of fishing equipment, there are lower parts of aline (casts), so called pre-lines (a part of line next to the hook), asreinforced line parts by which there is solved te technical problem oftensile and gliding strength of these most loaded parts of lines.Pre-lines are made of metal, mostly steel wires with high mechanical andcorrosion-resistant characteristics. The problem of visibility ofpre-lines in water is solved by reducing their thickness which decreasestheir mechanical characteristics and painting, which make them moreexpensive as products.

In the family of patent documents made of documents WO8810067,EP0321465, U.S. Pat. No. 5,035,075, U.S. Pat. No. 4,831,767, U.S. Pat.No. 4,674,223 and JP2500561T, there is described an artificial bait withmechanism for setting in motion parts of bait imitating fish fins orfrog legs. The mechanism consists of reel, on which there is winded thelower part of a line and which is fixedly supported on the rotating axisof the blade coil spring of the mechanism for transport andtransformation of rotational motion of the axis into alternate motion ofbait limbs, spring housing and transport mechanism, as well as the limbsof the bait themselves. All parts of the mechanism, except limbs, arearranged in the bait. The motion of bait limbs is made by pulling theline out of the bait, whereby the line is unwinding from the reel andthe blade coil spring is strained. The line is winding on the reel bymenas of blade coil spring, which inner movable part is fixed to therotation axis and the external fixed end to the fixed housing of thespring and transport mechanism.

By pulling the lower part of a line (cast) the bait is dragged, which isbecasue of water resistance, moving slower than the line itself. Throughit, the line is unwound from the reel for the length that is equal tothe difference of passed paths of the line and the bait. When thetensile strength in the line becomes smaller than the resistancestrength of water, having effect to the bait, the blade coil springreleases the cummulated potential energy and pulls the line into thebait, whereby it is winding on the reed again. By alternate pulling theline from the bait and its pulling in by means of blade coil spring,motion of bait limbs take place.

The described mechanism has been exclusively intended for setting inmotion parts of artificial bait, imitating limbs of natural bait whenthe bait is moving through the water. The lower part of line winding andunwinding on the reel is not the subject of patent protection.

The patent document U.S. Pat. No. 2,950,559 describes artificial baitwith the device for winding and unwinding the lower part of fishingline. The bait consists of two-part housing in which the springmechanism is placed. The housing consists of the front imitating thehead of a fish and the rear part imitating the body of a fish. Thespring mechanism consists of lifting tackle round which there is woundthe lower part of a fishing line and two drawing ropes strained by thepressure spring installed in the housing body. This solultion of windingand unwinding the lower part of fishing line is not in anyconstructional detail of the housing or spring mechanism similar to thesolution contained in this invention.

The patent document U.S. Pat. No. 5,029,410 also describes artificialbait with the device for winding and unwinding the lower part of fishingline. The bait consists of a two-part housing in which there is put thespring mechanism with the device for fixing the position of the lowerpart of fishing line. By longitudinal vertical symmetry plane, thehousing is divided in the left and right half between which there isinstalled the spring mechanism. Spring mechanism consists of doublelifting tackle on the axis, bedded in the housing. On one lifting tacklethere is wound a rubber ribbon or spring and on the lower part offishing line. Movable end of a rubber ribbon or spring is fastened tothe lifting tackle axis an the fixed one to the bait housing. Thissolution is in some constructional details of housing similar to thesolution contained in this invention. Consstructional solutions ofspring mechanisms are fully different. In the solution described in thepatent document U.S. Pat. No. 5,029,410 transfer of strengths andmovements from the rubber ribbon or spring to the lower part of fishingline and vice versa is done through the double lifting tackle on therotation axis, whereas in the solution described in this invention,transfer of strengths and movements from the spring to the lower part offishing line and vice versa is done through a hollow cylinder on thefixed axis. The spring is on the whole installed in the hollow cylinderand the lower part of fishing line is led by grooves on the externalsurface of a cylinder collar. The constructional solution of springmechanism according to the invention makes this device simplier and morereliable than the solution described in the document U.S. Pat. No.5,029,410.

DISCLOSURE OF THE INVENTION

The device for winding and unwinding the lower part of the fishing lineaccording to the invention, consists of two-piece shell-like housing inwhich the spring mechanism is arranged, for pulling in the lower,reinforced line into the housing or pulling the lower, reinforced partof the line out of the housing. The spring mechanism consists of thehollow cylinder supported on the fixed axis, fastened to one half of thehousing and blade coil spring put in the hollow in the cylinder. Theinternal fixed end of the spring is fastened to the fixex axis of thecylinder and its movable external end to the ring of the cylinder. Bydirect connection of the cylinder and spring, the interacting transferof motion from the cylinder to the spring and from the spring to thecylinder, takes place. On the ring of the cylinder there is a spiralgroove for the line. The inner part of a line is pulled through theradial opening on the ring of a cylinder, wound around the bearingsleeve of the cylinder and fastened with the stirrup to the line. Thejoined piece of the line is wound in the groove on the ring of cylinder.The external end of the line ends with a ring leaning against theexternal part of the opening for a line on the housing of a device.

When the bait with the device is in a passive state of resting or movingthrough the water when water resistance force is smaller than thepretension of the spring, the lower part of the line remains completelywound round the ring of the cylinder. The ring of the external end ofline is then leant to the external part of the opening for line on thehousing of the device because of effect of pretension force in thespring. In this way the whole lower part of the line is invisible,because it is wound in relatively small housing of a device that makes apart of the bait which effect of attracting fish is not disturbed by thevisible lower part of a line.

By stronger dragging the bait backward or sideward, that is happeningwhen the fis swallows, tears and draggs the bait, the lower part of aline is draeing out of the device. In the field of effect of a fish jaw,there is the pulled out, reinforced lower part of the line that can notbe bitten or torn off by a fish. In this way the reliable fishing isenabled without damage to equipment and loss of a catch.

Because of spring force effect in the device, the fish catched on thebait with this device is by additional spring force pulled forward whichdiminishes the possibility of her escape from the bait.

The device for winding and unwinding of the lower part of a line (cast)for fishing belongs to baits or type of device for holding baits on ahook, that are inserted in natural or artificial baits or to whichnatural or artificial baits are fastened. The device in form of insertrepreseents the universal part, applicable for all types of baitsfastened to the lower part of lines with a high tensile and glidingstrenth that are invisible in the stage of attracting fish. By thedevice, the set aim of finding the solution for invisibility in water ofa lower, reinforced, nontransparent metal part of the line in a stage ofattracting fish and effective and resistant to high tensile and glidingstresses in stages of swallowing, tearing and pulling the bait isachieved in the whole, by which the total exploitability of fishingequipment is encreased.

The solution according to the invention solved the problem ofeffectiveness of bait attractivenes and effectiveness of the lower partof a line, whereas by the solution described in the mentioned family ofpatent documents there is solved only the problem of effectiveness ofbait attractiveness. By the solution according to the invention inrelation to the solution described in the mentioned family of patentdocuments, the set aim of increasing the effectiveness of baitattractiveness is achieved in essentially different way, withessentially different construction and with essentially differentleffects of these solutions.

Attractiveness of the bait in the solution described in the mentionedpatent family is solved by setting in motion limbs of a bait only whenit is moving through the water, whereas the same problem in thedescribed invention is solved by pulling the lower visible part of aline into the bait when the bait is either resting in water or movingthrough the water.

The solution described in the mentioned family of patent documentsconsists of a device consisting of complex multupart spring mechanism inwhich the reel and spring are separated and in which there is arrangedthe movable internal end of a spring and the axis fastened to theexternal end of a spring. Fastening of the internal end of a line andits conducting on the strake of the reel is not clearly defined. Themechanism for transfer of rotation motion of the spring mechanism axisto the oscillating motion of bait limbs is a complex and expensivemechanism.

The spring mechanism of the solution according to the invention consistsof the cylinder and spring arranged in the cylinder. The fixed internalend of a spring is fastened to the fixed axis and the movable externalend of the spring directly to the cylinder strake. Fastening of theinternal end of line and its conducting on the strake of a reel isclearly defined and does not allow the line getting stuck andoverstressing the spring outside the field of elastic deformation.

By the solution according to the invention in relation to the solutiondescribed in the mentioned family of patent documents, except improvingthe effect of bait attractiveness in resting position and movement,there is also achieved the effec of increase of mechanicalcharacteristics of the lower line part (cast). According to theinvention, the lower line part may have significantly biggercross-section than the cast and could be made of materials, visible inwater, resistant to large tenside and gliding stresses as e.g. metalmaterials, whereas in the solution described in the mentioned family ofpatent documents, the cast is not the matter of patent protection.

DESCRIPTION OF THE CONSTRUCTION

A device 1 for winding and unwinding the lower part of fishing line(cast) shown on FIGS. 1 to 7, consists of housing, spring mechanism,lower line part (cast) and parts for acceptance of baits and hooks.

The housing has a form of extended shell consisting of the lower 2 andupper part 3, which external mantles are speculary symmetrical and whichare decomposably connected. The connection of the lower part 2 of thehousing and the upper part 3 of the housing is made as a tight seatconnection of internal overhangs 4 of one part entering in recesses inthe other part of a housing. In the widest part of a housing there is acylindrical hollow 6 for arrangement of a spring mechanism. In themiddle of the hollow 6 there is the axis 7, which lower part isdecomposably connected with the lower part 2 of the housing and whichfree upper end enters in the recess 8 in the upper part 3 of thehousing. In the upper part of the axis 7 there is the slot 9 which depthis larger than the half of the lenght of the axis 7. In the front partof the housing there is the axial channel 10 by which the hollow 6 isconnected with the outlet opening 11. In the rare part of the housingthere is axial bore hole 12 with vertical hole 13 in the lower part 2 ofthe housing. The housing is made of water resistant materials aspolymeric materials.

In the cylindrical hollow 6 of the housing, there is arranged the springmechanism consisting of the hollow cylinder 14 rotationally bedded onthe axis 15 turned to the upper part 3 of the housing. The internal,fixed end 16 of the spring 15 is inserted in the 9 on the upper part ofthe axis 7 and its external, movable end 17 is wound round the tooth 18on the strake of cylinder 14 in the opposite direction from thedirection of the spring curve 15 and tightened on the internal area 19of the cylinder strake 14. On the external area of the cylinder ring 14there is curve groove 20 round which the lower part of the line 21 iswound. Internal end 22 of the line 21 is dragged through the radialopening 23 on the cylinder ring 14, wound round the bearing sleeve 24 inthe groove 25 and fastened by the stirrup 26 to the line 21. Theexternal end 27 of the line 21, dragged through the channel 10 of thehousing ends with the ring 28 leaning against the opening 11 of thehousing.

In the initial position, the spring 15 is wound in the way, that theexternal 27 of the line 21 which is through the ring 28 leaning againstthe opening 11 of the housing is under the pretension force. Thepretension force of the spring 15 should be higher than the weight ofthe device with the bait in the water and higher than water resistanceforce to the motion of device with bait through the water. Under suchcircumstances, the lower part (cast) of line 21 shall in all usingcircumstances be pulled in the device and invisible for the catch.

In the utmost pulled out position, the lower part of a line 21 shall becompletely unwound from the cylinder 14, to which it remains connectedthrough the sleeve 24 by the internal end 22. At unwinding the line 21from the cylinder 14, the spring 15 in which the force is increasing,shall wind up. In order that the lower part of the line (cast) 21 couldunwind from the cylinder 14 in the whole, the work deflection of thespring 15 representing the total deflection of the spring 15, reducedfor the pretension deflection, to be larger than wound length of thelower part of line 21, in order of correct functioning of the spring 15in the field of elastic deformation. In the utmost pulled out position,to which it comes in case of heavy catch, the total weight force ofdevice, baits and catch, as well as water resistance is transferec bythe lower part of line 21 over the sleeve 24 to the axis 7. In this was,at the time of highest tensile forces, the cylinder strake 14 isdisburdened and the axis 7 as the strongest part of the device, isloaded. Upon disappearance of external tensile forces, the strainedspring 15 pulls the lower part of lilne 21 in the device, whereby it iswounded on the strake of cylinder 14, until the ring 28 does not leanagain against the opening 11 of the housing.

Parts of spring mechanism and the lower part of line 21 and belongingpart should also be made of water resistant materials as polymericmaterials and corossion resistant metal materials. For cylinder 14 itwould be the best to manufacture it of water resistant polymericmaterials, whereas the blade coil spring 15, lower part of the line(21), stirrup 26 and ring 28, should be made of corrosion resistantsteel materials with high tensile and gliding strength.

In the front part of the device housing there is fastened the metalstirrup 29, to which by short lines 30 there is connected one or moremetal hooks 31. In the axial bore hole 21 of the housing there isinserted the bearing 32 of baids in the form of metal rod, whichinternal end 33 is bent under right angle and inserted in vertical hole13 in the lower part 2 of the housing. The external end 34 of thebearing 32 is bent under the angle exceeding 90° in the hook for baits.
